To all whom it may concern:

Be it known that I, HEMAN D. TI-IAYER,

a citizen of the United States, residing at lonneaut, in the county ofAshtabula and State of Ohio, have invented certain new and usefulImprovements in Apparatus for Treating the Soil, of which the followingis a specification.

This invention relates to improvements in agricultural implements andparticularly to thalt class of devices utilized in treating the $01 Moreparticularly the invention relates to apparatus for controlling thesupply of live steam to mechanism which conveys it to the soil under thesurface thereof, without useless waste, for killing pests of variouskinds and doing away with weeds and other unmarized as consisting in theconstruction desirable crops which seed themselves from one season tothe other.

The invention may be further briefly sumand combination of partshereinafter set forth in the following description, drawings and claims.

Referring to the drawings, Figure 1 is a side elevation of a machineadapted for the purpose and arranged to be drawn in any suitable mannerover the soil; Fig.2 is a longitudinal section of the feeding drum; Fig.3 is a view of the developed periphery of the drum; Fig. 4 is a sectionupon the line 4-4 of Fig. 2 looking in the direction of the arrows; Fig.5 is a section through the steam supplying means for the drum; and Fig.6 is a view partly in section showing a portion of one of the spines orsteam supplying tubes.

In carrying out the invention any pre ferred form and construction ofparts may be employed but I have shown one arrangement which iseffective in operation and in such embodiment 1 represents a steamboiler of any desired type for supplying steam to the apparatus. Thisboiler is mounted upon a suitable truck 2 supported upon steering wheels3 and .carrying a suitable bracket 4 which are mounted upon the shaft 5of the steam feeding drum to be described.-

The steam feeding drum comprises a head 6 secured to the shaftby screw 7and having mounte a drum 8. This drum is opposite end with a head, 9secured to the shaft by mea 11. This head is cored out ally disposedopenings or p to a suitable chamber 13 f4 head. Each of these ports witha longitudinally dis 14 threaded into the hea through suitable openingswill be seen from the foreg a radially disposed port 1 steam pipes 14.

Rotatably mounted with: is a valve member 15 held her by means of anannulz to the head by means of valve member is cut awa in the variousfigures, so a more of the ports 12, as This valve member 15 is port 19establishing comn steam supply pipe 20 low ling valve 21, this valve b asuitable pipe 22 with th the steam pipes 14is pro rality of spines orsteam extending therefrom thn and. at a distance from th of these spinesor dischar; vided with a point24 an ings 25 on the side, as she rows ofspines or discha] gered, as shown in Fig. 3 tween adjacent rows areplates 26 having flanges drum. These blades exte of the drum and formrows of spines or discha ends of the drum suita' provided, and theseflang by suitable base flanges drum in any suitable m. 26 extend fromthe Hang flanges and plates closed about the rows of spines, pocketsbeing such that rolled over the ground th embed themselves in the soiland the discharge of steam from the spines is confined to a small areaand is not permitted to discharge freely through the soil. These platesand flanges also prevent the steam from blowing the soil away as wouldbe the case where it was soft and light. The valve 15 is to be adjustedso that the cut away portion 18. which forms the steam supply pocket, istoward the ground, as shown, and in order to insure this arrangement thevalve is held against rotation by means of a bolt or cap screw 30extending through one of the brackets 4 into the valve.

From the foregoing it will be seen that as the apparatus is drawn overthe ground, the spines, the plates and the flanges will embed themselvesin the soil and steam will be supplied to those embedded in the soil bymeans of the valve member already described. As the steam is supplied tothe soil, it passes into it and kills worms and bugs of everydescription, which are detrimental to growing things and also killsundesirable crops of weeds and the like which seed themselves from oneseason to the other.

Having described my invention, I claim 1. In apparatus for treating thesoil, a steam supply, and means for delivering steam to a plurality ofdischarge devices adapted to embed themselves in the soil withoutdisturbing the surface thereof and supply steam thereto under suchsurface, said discharge devices being isolated one from the other underthe soil.

2. In apparatus for treating the soil, a steam supply, a rotary memberhaving devices for supplying the steam to the soil under the surfacethereof, and means for directing a supply of steam to only such of saiddevices as are embedded in the soil.

3. In apparatus for treating the soil, a steam supply, a rotary memberhaving devices for supplying the steam to the soil under the surfacethereof, and valve mechanism for directing a supply of steam to onlysuch of said devices as are embedded in the soil.

4. In apparatus for treating the soil, a steam supply, a rotary memberhaving devices for supplying the steam to the soil under the surfacethereof, means for controlling a supply of steam to only such of saiddevices as are embedded in the soil, and means for directing the steamsupplied to the soil and preventing the blowing of the soil.

5. In apparatus for treating the soil, a steam supply, a rotary memberhaving devices for supplying the steam to the soil under the surfacethereof, means for controlling a supply of steam to only such of saiddevices as are embedded in the soil, and confining pockets formed aboutthe steam supplying, devices.
